seems well built... my sister uses it more and her boyfriend bought an e-99 spyder... and he wants her marker... feels he paid too much for his by comparison to the quality...
trigger is sweet nice and easy to get a good rate off... not that many upgrades avaliable over here... but have seen bolts and triggers over your side of the pond...
buying a marker is like buying a car...
sod what the reviews say and personal views... try it, like it, buy it...
